To my surprise it was written by Anne Stanton(yes aka crmlady), so I just gave it quick look, but my review will follow later. Very curious what tips & tricks I could learn :-)
The second one really got my attention because it was called "Microsoft Dynamics CRM 4 Integration" by Marc J. Wolenik & Rajya Vardhan Bhaiya and it has topics about SharePoint and my fav tool Scribe Insight. In my quick look I also so remarketed term xRM e.g. extending crm.. which we did already in 3.0....
I hope to write something about by end of next week.
Keep reading books :-)
PS Just finished Dan Brown's Lost Symbol
